[AArch64][SVE] Asm: Support for vector element compares.
This patch adds instructions for comparing elements from two vectors, e.g.
cmpgt p0.s, p0/z, z0.s, z1.s
and also adds support for comparing to a 64-bit wide element vector, e.g.
cmpgt p0.s, p0/z, z0.s, z1.d
The patch also contains aliases for certain comparisons, e.g.:
cmple p0.s, p0/z, z0.s, z1.s => cmpge p0.s, p0/z, z1.s, z0.s
cmplo p0.s, p0/z, z0.s, z1.s => cmphi p0.s, p0/z, z1.s, z0.s
cmpls p0.s, p0/z, z0.s, z1.s => cmphs p0.s, p0/z, z1.s, z0.s
cmplt p0.s, p0/z, z0.s, z1.s => cmpgt p0.s, p0/z, z1.s, z0.s
